PROBLEM TO BE SOLVED: To provide an estimating method by which the health condition of a patient can highly precisely be evaluated from nutrition evaluation items (biochemical examination values) of the patient.SOLUTION: In this method for evaluating the health condition of the patient, (A) at the starting of a nutrition management, the hematocrit which is the biochemical examination value of the patient, the urea nitrogen concentration in blood, the albumin concentration in blood, and the zinc concentration in blood are measured. Also, (B) an SPI (simple prognosis index) value is calculated by respectively substituting each biochemical examination value having been measured in the following formula (1) SPI=a0+a1×Hct+a2×BUN+a3×ALB+a4×Zn (in formula (1), a0, a1, a2, a3 and a4 are partial regression coefficients which are obtained by performing a linear multiple regression analysis). Then, (C) when the obtained SPI value is at a preset reference value or higher, the health condition is judged to be preferable, and when the obtained SPI value is less than the reference value, the health condition is judged to be poor by the patients health condition evaluating method.COPYRIGHT: (C)2010,JPO&INPIT【課題】患者の栄養評価項目(生化学検査値)から患者の健康状態を高い精度で評価することのできる予測方法の提供。【解決手段】患者の健康状態を評価する方法であって、(A)栄養管理の開始時に患者の生化学検査値であるヘマトクリット、血中尿素窒素濃度、血中アルブミン濃度および血中亜鉛濃度を測定し、(B)測定した各生化学検査値をそれぞれ下記式(1)に代入することによりSPI(簡易予後指数)値を算出し、(C)得られたSPI値があらかじめ設定した基準値以上である場合は健康であり、該基準値未満である場合は健康でないと判定する、患者の健康状態評価方法。SPI=a0+a1×Hct+a2×BUN+a3×ALB+a4×Zn (1)(式(1)において、a0、a1、a2、a3およびa4は、線形重回帰分析を行うことにより求めた偏回帰係数である。)。【選択図】図1
